Applying nonlinear forces
Steven Dinsdale Aug 8, 2008 5:43 PM (in response to Brendan L)Personally, I would apply the lift over the whole surface. If the solution takes too long you could try the point method but I don't think that will give you the same results. I would recommend rerunning it with 23X the number of points until the solution converges and along many lines.

Applying nonlinear forces
Bill McEachern Aug 11, 2008 1:27 PM (in response to Brendan L)You could add another split line so you get a surface that approximates the "line" (ie a narrow surface. Otherwise you could put a linear distribution in the free stream direction along with the elliptical one in the transverse tot he free stream which is what is typically done. The nonlinear load distribution has this capability. You can check it by comparing he root loads or stresses with a point load approximation.

Sara Stults Aug 13, 2008 1:24 PM (in response to Bill McEachern)Thanks everyone! (I'm the original poster, I used my coworker's account to post my question by mistake.)
I ended up using several point loads along the line to approximate it for now, and I'm going to try modifying my equation to use 3D data instead of 2D data so I can apply it over the entire surface as a pressure load instead of a force. Hopefully this will be more accurate and I won't get stress concentrations around the force points.
Thanks for the advice, it really helped!
